A cool ride for the responsible

A car's cooling system is crucial to engine longevity. When a car overheats, the resulting damage is often severe enough to require an engine overhaul. It is important to make sure the cooling system is always in good working order. Taking a few preventative measures may increase the life of your engine significantly.

The cooling system is comprised of a number of components. Many of these components are rubber hoses and seals which are susceptible to wear and corrosion, and if broken, can quickly lead to engine failure.

There are several signs that indicate a corroded or damaged coolant hose. Inflexible or brittle rubber hoses should be replaced as soon as possible. Hoses with bulges or kinks are also on their way out. If a hose is already leaking, it may be accompanied by steam and a sweet smell.

Many of today's cars use coolant hoses that are specially shaped to navigate around different engine components. Some parts of the cooling system may not be easily accessible, and some may not be visible. A general rule is that a car's coolant hoses should be replaced every four years, though some may last significantly longer.

Replacing damaged or deteriorating hoses will prevent overheating and wear on major engine components. A modern engine's moving parts are built with tight tolerances and may be especially susceptible to heat damage. Once overheated, these components expand beyond their tolerances and the engine begins to break down from friction.

It is imperative to stop any coolant leaks as soon as they happen. It may be a good idea to keep some duct tape and a few sections of spare coolant hose in your car's emergency kit.

If your hoses are showing signs of wear, it may be time to see an ASE certified mechanic. Other cooling-related maintenance may be needed, such as a cooling system flush or a new thermostat. A good mechanic may offer other preventative suggestions that will keep your car on the road for many years.
